Scintigraphic differentiation of intrahepatic tumors
Intrahepatic tumors in asymptomatic patients are seen with increasing frequency. Treatment is dependent of the histology; while follicular nodular hyperplasia (FNH) and hemangiomas need no further treatment, all other tumors should be resected. In a prospective study we investigated the usefulness of two-stage scintigraphy (TSS) for the differentiation. The cholescintigraphy was started with a perfusion study, followed by a scan in the parenchymal phase and in the excretion phase. There is a typical scintigraphic pattern for FNH (hyperperfusion, normal parenchymal uptake delayed excretion) and hemangioma (hypoperfusion, no uptake), while all other tumors may have a mixed pattern. Therefore a blood pool is added to look for a hemangioma, if there is no typical pattern for FNH in the cholescintigraphy. The TSS classified correct 21 of 23 patients with FNH, 17 of 18 with hemangiomas, all 3 with adenoma and 36 of 37 with primary malignant intrahepatic tumors. The TSS is more accurate than CT or sonography, safe and inexpensive and therefore the method of first choice in the differentiation of intrahepatic tumors.
